No. 810,267. Specification of Letters Patent. Patented Jan. 16, 1906.Application filed February 27, 1905. Serial No, 247,486.

ToaZZ whom it may concern..-

Be it known that I, JOSEPH E. DRAKE, a citizen ofthe United States, anda resident of Blue Rapids, in the county of Marshall and State ofKansas, have invented a new and Improved Grain-Door, of which thefollowing is a full, clear, and exact description.

My invention relates to grain-doors for such structures as railway-cars,it being an ro improvement upon my Patent N o. 740,407, dated October 6,1903. Its principal objects are to facilitate the opening of the doorand to otherwise improve the organization.

Reference is to be had to the accompanyi 5 ing drawings, forming a partof this specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a horizontal section through a car to which one embodimentof my invenzo tion is applied, the view being taken looking upwardly andshowing the doors in a raised position. Fig. 2 is a transverse verticalsection on the line 2 2 of Fig. 1. Fig. 3 is a detail in elevation,showing the inner side of one of the doors and its guide. Fig. 4 is asectional detail through the upper edge of the door and particularlyillustrating the supporting means, and Fig. 5 shows in perspective oneof the carriers. i

3o I have here illustrated a car A, having in its opposite sides theusual door-openings B B. Extending above and to one side of each doorand longitudinally of the car is a guide 10, preferably consisting of ahol- 3 5 low or tubular bar supported by brackets 11. At the inner sideof each guide-bar is a longitudinal slot 12, this lying in a horizontalplane and being shown as closed at one end. At its opposite end it mayextend for the full 4o length of the bar, there being provided a stopwhich may consist of a pin 13, which is secured to the car by a chain orflexible memextends outside the guide and has rotatable upon itsupturned cylindrical end a roll 2() for contact with the guide. Securedto each pair of supports is a door O. This includes a 6o frame havingside members 2l 21, connected by an upper member 22, these elementsbeing preferably braced at their junctures 23. Secured to the oppositeextremities of the side members is a lower member 24, which is divided,there being at its center a space. The frame members 21 and 22 areconveniently formed from angle-iron having one liange extendingoutwardly from the car. Between the members 22 and 24 the side membersare 7o connected by'a cross-bar 25, `also of angleiron and having aflange extending inwardly. Secured across the top of each door-frame atits inner side is a supporting-strip 26, which may be of wood, and tothis is connected an upper door-section 27 by means of hinges 28. Thisdoor-section at its lower edge coacts with the cross-bar, which servesas a sill for it. Each door-section is provided with a securing device,which, as illustrated, is in the 8o form of a hasp 29, projectingthrough an opening in the vertical flange of the crossbar and engaged bya hook 30, pivoted upon said flange. Fastened upon the inner side ofeach door-frame below the cross-bar is a fixed door-section 31, whichmay be shod at its lower edge with an angle-iron 32. In this section isa space 33, extending between the ends of the divided member 24 forsubstantially half the distance between it and the 9o cross-bar.Connecting the adjacent extremities of the member 24 and the bar 25 areseparated vertical bars 34, which strengthen the structure and alsoserve as guides or ways for a panel 35, which may occupy and close thespace 33 or be slid upwardly to free it. The panel is shown as providedwith transverse reinforcing-strips of angle-iron 36 and ber 14 andiitting alined openings 15 in the has a securing device, which mayconsist of a bar. In each guide-bar, opposite the doorbolt 37, carriedby the panel and capable of roo 45 opening and near each side thereof,are slot j coacting with eitherof tworecesses 38 and 39, enlargements oropenings 16, extending tothe former locking the panel when closing wardthe under side of the bar. the space and the latter in its raisedposition. Operating in each guide are supports (here Each of thecross-bars 25 is extended at its shown as two in number) and eachcomprisends 40 beyond the door, where there may 105 5o ing a cylindricalmember 17, iitting the holcoact with it securing devices or buttons 41,

This places the doors in a substantiallyhorizontal position, in which they will continue until the shanks reachthe slot enlargements, when they may be swung downwardly into coperationwith the door-openings. Here they may be secured by the buttons 41,access to these being had through the upper door-sections. Each panelnow being locked in its lowered position, the car may be filled throughone or both of the door-sections, and when this operation is completedsaid sections are themselves closed and locked in place. When it isdesired to unload the car, a panel is released and raised, allowing thecontents of the car to iow through the opening 33. When this dischargehas ceased, the doors may be freed by unlocking and raising the uppersections and turning back the buttons. Said doors may then besuccessively swung upwardly in the guides, the shanks turning in theslot enlargements. When they are in a substantially horizontal position,means are provided for securing them in place. As illustrated, each doorhas associated with it and hung from the car-roof near its inner raisedend a tubular bar 42, depending from brackets 43 and having in its underside a slot 44, from which opens an enlargement 45, located opposite thedoorspace 33. In the bar-channel operates the cylindrical portion 46 ofa carrier, which also has a depending shank 47, from which extendopposite engaging projections 48 and 48a. When the carrier-shank liesopposite the slot enlargement, the engaging projection 48 may be swungaway from the door, the shank lying in a horizontal plane. rIhe doorhaving been raised, this projection may be turned downwardly, enteringthe space 33 and engaging the lower or inner extremity of the panel, andthus securely supporting the door in its raised position. At this timethe Shanks of both the door-supports and the carrier are in alinementwith the guide-slots, enabling both door and carrier to be slidlongitudinally of the car, so th at they will be out of the way. In thistravel the support-roll rests upon the upper side of the guide, as isparticularly illustrated in Fig. 4 of the drawings, facilitatingmovement. The projection 48a servesl to engage and retain thedoorsection 27 in its raised position.

IIaving thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination with a car having a door-opening,of a hollow guide extending longitudinally of the car above the opening,a supporting member iixed upon the door and being movable through androtatable in the guide, and an arm extending from the support and havingmeans overlying and contacting with the guide during the rotation of thesupporting member.

2. The combination with a car having a door-opening, of a hollow guideextending longitudinally of the car above the opening, a supportingmember fixed upon the door and being movable through and rotatable inthe guide, an arm extending Jfrom the support outside the guide, and aroll upon the arm contacting with the guide throughout the rotation ofthe supporting member.

3. A grain-car door, comprising a frame having side members and across-bar connecting the side members between their ends, and having itsends projecting beyond the same, a lower fixed door-section secured tothe side members of the frame at one side of the cross-bar, and an upperdoorsection hinged at its upper edge to the frame and having its freelower edge engaging the cross-bar.

In testimony whereof I have signed my name to this speciiication in thepresence of two subscribing witnesses.

JOSEPH E. DRAKE.
